BOULDER — Sophomore defensive back Sherrard Harrington is taking a medical redshirt. Out of Washington’s Howard D. Woodson High, Harrington suffered hip and knee injuries during his redshirt freshman season in 2011 and he didn’t record a statistic last year.

“His hip had bothered him before and it was starting to bother him (again),” first-year coach Mike MacIntyre said after Tuesday’s practice. “We all know how hips are. It’s been nagging him a lot. He hasn’t been able to go full speed all the time.”

BOULDER — This week’s snow forced Colorado’s third spring practice Tuesday, their first in pads, into the practice bubble. One of the conditions of new coach Mike MacIntyre’s hiring is an improvement in facilities and that includes a permanent indoor practice facility.

For now, he’s fine with the bubble next to the practice fields below Folsom Field.

“I like it,” MacIntyre said. “It works good. It’s better than slopping around in the snow right now or being in a gym. I love this FieldTurf. It’s good FieldTurf. I’m glad it’s FieldTurf and not AstroTurf. That’s for sure.”

BOULDER — Colorado’s pro day is Wednesday morning and tight end Nick Kasa, the only Buffalo who attended the NFL Combine, said Tuesday he will not run the 40.

Kasa pulled his hamstring during his 40-yard dash at the Combine but it was at the end and he still ran a 4.7, more than enough to satisfy teams.

Kasa, who attended Colorado’s spring practice in the practice bubble, said his leg is fine and said, “I really want to get a 4.6 but it’s just too risky.”

He will do the agility drill, the three-cone drill and catch passes. Teams are intrigued by the converted defensive end from Legacy High who caught 25 passes for 391 yards and three touchdowns in his only full season at the position last year.

LAS VEGAS – Colorado’s Tad Boyle received the best news any coach could receive Tuesday — his best player, junior forward Andre Roberson, was cleared by doctors and will be in the starting lineup Wednesday afternoon in an opening round game of the Pac-12 Tournament at the MGM Garden Arena.

Roberson has missed two games with mononucleosis. He leads the nation in rebounding (11.5) and tops the Pac-12 in steals (2.25) in addition to averaging 10.8 points per game.

“We worked a little bit of zone offense today,” Boyle said, “and Andre got two or three offensive rebounds. That’s one thing he brings.

I abhor 10-man all-conference basketball teams. Hey, just make a first team and a second team, and let’s not give ribbons to everyone.

But it is a feather in the cap of Colorado coach Tad Boyle that two players he brought to Colorado — junior forward Andre Roberson and sophomore guard Spencer Dinwiddie — were voted among the top 10 players in the Pac-12 Conference.

That’s 20 percent of the Pac-12 team for a Colorado program that lacks the basketball tradition of other Pac-12 schools.

“It tells you we’re recruiting good players,” Boyle said.

“For Andre to develop into a defensive player, an all-league guy, says something about the players when they get in here,” he added.

“That’s what we tell (recruits): ‘We’re not going to just get you to Colorado and not have you get better. Hopefully, you’re going to improve while you’re here. That’s a testament to our coaching staff — their ability to recruit and to make guys better.”
